I don't know why some people despise the 90s and 2000 Jojo's compared to the 2010s Jojo's. These OVA are quite enjoyable. The strategic plays in this series are perfect for this style.
Like my first review of the JoJo series ->http://www.anime-planet.com/anime/jojos-bizarre-adventure/reviews, this anime expands and clues us in on the relationships between the characters, and tells us how the healing mother/daughter thing actually plays a role.
Pros: More up-to-date animation, the same intriguing and funny characters, better and a more intense storyline.
Cons: Sound is same as the original; mediocre at best without the cool horror end theme, and minimal, albeit good, fights.
This is what the first one in 1993 should have been good backstories so we know who they are and what their relationships are to one another. How Jotaro's mother became sick, and this one could've been the dio fight. Very good this is the "original" to the older one very good and very much worth the watch.
